The RAM layout in U-Boot was revised to accommodate larger kernels even for devices with only 256 MB or 512 MB of RAM. As part of that work, we decided to move the reserved memory for the ELE firmware, especially to optionally include OP-TEE in the first 256 MB of RAM. Move the address to 0x8a400000 and follow what was decided in U-Boot. Upstream-Status: Pending Signed-off-by: Ernest Van Hoecke <ernest.vanhoecke@toradex.com>

On the Toradex SMARC iMX95, the WiFi UART signals are shared with the JTAG. The WIFI_UART_EN signal is used to select between these two functions. A GPIO hog is used to select the UART function by default. The hog is safe as it is already configured in the same way by the boot firmware before Linux driver probing begins. Configure WIFI_UART_EN as a gpio-hog driven high.
